mrxme DEVICE.

Application medium 21,. 1923, Serial oughly commingle such products withthe fluid which is in the mixing container. The rapidit with which thiscan be done is my main 0 ject. Other objects are hereinafter set fort Iaccomplish these results by means of the device hereinafter describedand illustrated on the accompanying drawing, in which F igure 1 showsthe agitator andan inside view' of the container. Figure 2 is a separateview of two sides of the container, showing the shape of the vanestherein. Figure 3 is a sectional view ofthe screw along the line 3 inFigure 1. Figure 4 shows a modified I jacent to the bottom, in an upwarddirection,

form of propeller. The device consists of an agitator constructed with astem 4 having a screw thread 5 projecting from a portion of. said stem,and terminating at the bottom with an enlarged screw 6. A propeller 16shown in Figure 4 can be substituted for the screw 6.

I have formed three channels equidistant apart across the thread 5, buta smaller or larger number of such channels can be used. 7 is a nut atthe top of the stem to attach the bit, or agitator to a shaft 8 of amotor 18, or other source of power.

The container shown as 9 contains a pluralit of uniformlycurved vanes 10on the insi e thereof. In the drawing I have shown the containershaped'like an inverted frustum of a rectangular pyramid. The vanes areshown as beginnin at the lower right hand corner of the si e of thecontamer and' curving upwardly toward the right, the radius of the'curvedecreasing to ward the upper end. One of these vanes should be on eachof the four sides of the inside of the container. I do not want to beconfined to a container having four sides only inasmuch as it ispractical to use a container formed with a larger number, and with vanesformed on each of-the sides. Or the container can be the shape of aninverted frustum of a cone, or tubular, and a plurality of vanes canbeplaced inside starting at the bottom andcurving upward to- No.046,743.

ward the-left, The object of the vanes is to force the contents of thecup downward and to break or crush lumps and fruit which is in themixture in the cup. -It is also noted that the relative diameter of thescrews 5 and 6 are shown in the drawing and such relations should beadhered toapproximate- 1y: The screw 5 is approximately two-thirds thediameter of screw 6. The screw 6 should be proportionately short, towit, approxi-. mately one-sixth of the length of screw 5. The threads ofscrew 5 are broad at the base and taper to a sharp edge along thecircumference. The threads of screw 6- run opposite to the threads ofscrew 5, threads 5 being left handed. In using this device the agitatoris attached to the shaft of a motor or source of power which will giveit a rapid rotary motion in the direction of the travel of the hands ofa watch. When thus rotating, the screw or propeller 16 tends to throwthe contents of the cup, which is adand screw 5 tends to throw thecontents of the on downward. The sharpedges and broad ase of screw 5which is aided by the lateral channels 8 hereinbefore referred to, makesthe screw 5 act as a cutter and the rapid rotation of the agitator willchop, mangle or break the fruits, ice, ice cream, malt, and similaringredients into small particles and will assist in dissolving them. Thechannels 8 hereinbefore referred to serve to permit the fruit and othercontents of the bottom of the cup to be raised upwards so the knivesformed by the cutting portions of the screw 5 cancutsaid fruit.

In my experiment a mixer of this character will thoroughly mixingredients in one-fifththe time necessary to perform the same degree ofwork by other mixers now in use, and the construction of the vanes andscrews as described keeps the contents of thecontainer therein whilebeing agitated.

I claim as new and ask for Letters Patent v 1. In a mixer, incombination with acontainer, an agitator adapted to be rotated withinthe container, the agitator consistin of a stem having a circular platethreade on its periphery attached to the bottom, said stem having anenlarged diameter above the bein approximately one-half to two-thirdsthe iameter of the slate, said stem being adapted to be rotate 2. In amixer, in combination with a container an agitator consisting of a stemhaving an enlarged threaded head at the lower end, and a reversethreaded ortion adjacent to the head, said reverse t readed portionhavin transverse channels thereon, said agitator ieing adapted to berotated.

3. In a mixer, the combinationof a container having interior vanesextending upwardly and curving toward the left at the upper end thereof,and an agitator consisting of a stem terminating at the lower end with aright hand screw having an enlarged diameter, and having immediatelyabove the said lower screw, a left threaded screw of lesser diameterthan the lower screw, the left hand screw having channels cuttransversely across the threads, and means for rotating the agitatorclockwise, substantially as described.

4. In a mixer, the combination of a container having interior vanes, andan agitator adapted to be rotated vertically withinjthe container, theagitator having a screw propeller at the lower end, and a screw of lessdiameter and with reverse threads to the propeller immediately abovesaid propeller, and channels'being formed transversely and to the depthof the threads, substantially as PETER G. HINES.
